Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a splicing mechanism of a display screen and an electronic device. Background Art

[0002] With the continuous advancement of display technology, users' requirements for display devices are becoming increasingly higher. Compared to LCD and OLED displays, Micro-LED displays offer higher brightness, higher efficiency, shorter response times, longer lifespans, and wider operating ranges. They are considered the ultimate display, suitable for a variety of end products such as TVs, wearable devices, and smartphones. However, due to the extremely low yield rate of large-scale Micro-LED displays, the mainstream approach is to splice smaller Micro-LED displays into larger ones.

[0003] The current method of splicing display screens on the market generally includes: using positioning pins to locate a single display screen and connectors to install it on the splicing unit box, and then using positioning pins and spring locks to locate the splicing unit boxes to assemble the final splicing large screen.

[0004] In current splicing methods, each display panel is fixed in position once it's mounted on the splicing unit. The gap between adjacent panels is determined entirely by the precision of the locating pins. However, these pins typically have manufacturing tolerances, leading to uneven seams within existing spliced ​​screens, ultimately impacting the display quality. Summary of the Invention

[0005] In view of this, the present application provides a display screen splicing mechanism and an electronic device, which can accurately adjust the splicing gap between two display screens.

[0006] According to a first aspect of an embodiment of the present application, there is provided a splicing mechanism for a display screen, the splicing mechanism comprising: a support plate, wherein the number of the support plates is at least two, and at least two of the support plates are spliced ​​together; a connecting piece, wherein two adjacent support plates are connected by the connecting piece, and the splicing gap between the two adjacent support plates can be adjusted by the connecting piece; and a middle frame, wherein at least two of the support plates are mounted on the middle frame, wherein the support plate and the middle frame are relatively fixed by a binding force in a first direction, and the relative position between the support plate and the middle frame in a second direction can be adjusted by applying an external force, wherein the first direction is perpendicular to the extension direction of the support plate, and the second direction is parallel to the extension direction of the support plate.

[0007] A second aspect of an embodiment of the present application provides an electronic device, comprising at least two display screens and the above-mentioned splicing mechanism, wherein at least two of the display screens are fixed on at least two of the support plates.

[0008] The beneficial effects are: on the one hand, the present application accurately adjusts the splicing gap between two adjacent support plates through the connecting parts to ensure that the gap between the display screens meets the requirements; on the other hand, the setting of the middle frame can not only avoid the position of the adjusted support plate being affected by the position of the other support plate being adjusted during the splicing gap adjustment process, but also avoid the relative position between at least two support plates being offset due to factors such as transportation after the splicing gap adjustment is completed.

[0024] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] See Figures 1 to 3 In one embodiment of the present application, the splicing mechanism 1000 includes a support plate 1200 , a connecting member 1400 and a middle frame 1600 .

[0026] The number of the support plates 1200 is at least two, wherein Figures 1 to 3 Four are used for illustration, and at least two support plates 1200 are spliced ​​together.

[0027] In this embodiment, a single support plate 1200 is used to support a single display screen 2000, so the splicing gap between two adjacent support plates 1200 determines the splicing gap between two adjacent display screens 2000. In other words, the splicing gap between two adjacent display screens 2000 is adjusted by adjusting the splicing gap between two adjacent support plates 1200.

[0028] In an application scenario, such as Figure 4 As shown, the display screen 2000 is fixed to the support plate 1200 by means of frame glue 1100. In other application scenarios, the display screen 2000 can also be fixed to the support plate 1200 by other means such as snap-fitting, magnetic fixing, screw locking, etc.

[0029] It is understood that, in order to ensure that the splicing gap between two adjacent display screens 2000 meets the requirements, the cross-section of the support plate 1200 perpendicular to the thickness direction is smaller than the cross-section of the display screen 2000 perpendicular to the thickness direction. In other words, when the display screen 2000 is fixed to the support plate 1200, the support plate 1200 is confined to the range covered by the display screen 2000 and does not protrude from the display screen 2000. In other words, the support plate 1200 is completely obscured by the display screen 2000 and does not appear. For example, the support plate 1200 and the display screen 2000 are both rectangular in shape, concentrically arranged, and the length and width of the support plate 1200 are smaller than the length and width of the display screen 2000.

[0030] Among them combined Figure 4 and Figure 5 The non-display surface of the display screen 2000 in this application is provided with a connector 2001 for introducing a driving signal to enable the display screen 2000 to display a picture. In order to allow the connector 2001 to be connected to an external circuit to introduce a driving signal, the support plate 1200 is provided with a first opening A corresponding to the connector 2001. When the display screen 2000 is installed on the support plate 1200, the connector 2001 is exposed in the first opening A.

[0031] Considering that the position of the display screen 2000 changes as the seams are adjusted, the final locked position of the display screen 2000 cannot be accurately determined before assembly. Therefore, to prevent the connector 2001 on the subsequent display screen 2000 from being unable to accurately mate with the output port of the drive signal, the connector 2001 of each display screen 2000 is connected to a connecting wire 2100, which extends outward through the first opening A on the support plate 1200. Specifically, the connecting wire 2100 is bendable, which reserves space for adjusting the position of the display screen 2000. That is, the connecting wire 2100 can be bent to accurately mate with the output port of the drive signal.

[0032] It should be noted that, in other embodiments, when the display screen 2000 is relatively large, two, three, or other multiple support plates 1200 may be used to simultaneously support a single display screen 2000 , or one support plate 1200 may be used to simultaneously support multiple display screens 2000 .

[0033] Continue reading Figure 3 The two adjacent support plates 1200 are connected by a connector 1400 , and the splicing gap between the two adjacent support plates 1200 can be adjusted through the connector 1400 .

[0034] Specifically, the connector 1400 can precisely adjust the gap between two adjacent support plates 1200 so that the gap between the two adjacent support plates 1200 meets the requirements. The gap between the two adjacent support plates 1200 can be adjusted by adjusting the position where the connector 1400 is connected to at least one of the two adjacent support plates 1200, for example, by connecting the connector 1400 to different parts of the support plates 1200, or by adjusting the length or angle of the connector 1400 itself.

[0035] Continue reading Figure 3 At least two support plates 1200 are installed on the middle frame 1600, wherein the support plates 1200 and the middle frame 1600 are relatively fixed by a binding force in a first direction, and the relative position of the support plates 1200 and the middle frame 1600 in a second direction can be adjusted by applying an external force, wherein the first direction is perpendicular to the extension direction of the support plates 1200, and the second direction is parallel to the extension direction of the support plates 1200.

[0036] Specifically, when no external force is applied to the support plate 1200 and the middle frame 1600, the support plate 1200 and the middle frame 1600 are relatively fixed by the binding force in the first direction, and the two remain in a relatively static state. When external force is applied to the support plate 1200 and the middle frame 1600, the relative position of the support plate 1200 and the middle frame 1600 in the second direction changes, thereby achieving adjustment of the splicing gap between the support plates 1200.

[0037] During the assembly process, at least two support plates 1200 are first spliced ​​together using the connector 1400 and fixed to the middle frame 1600. When no external force is applied to the support plates 1200 and the middle frame 1600, the support plates 1200 and the middle frame 1600 remain relatively stationary. When the splicing gap between two adjacent support plates 1200 needs to be adjusted, the adjustment is performed using the connector 1400. When the splicing gap is adjusted using the connector 1400, an external force is applied to the corresponding support plate 1200, causing the corresponding support plate 1200 to move relative to the middle frame 1600 in the second direction. At this time, the support plate 1200 to which no external force is applied remains stationary on the middle frame 1600. After the adjustment is completed, as the external force is removed, the at least two support plates 1200 are fixed to the middle frame 1600.

[0038] That is to say, the middle frame 1600 can support at least two support plates 1200 without affecting the adjustment of the seam between two adjacent support plates 1200.

[0039] It can be seen from the above assembly process that the middle frame 1600 can support and fix at least two support plates 1200 during the process of adjusting the splicing gap, but will not fix the at least two support plates 1200, so that the position of the support plates 1200 is adjustable; and after the splicing gap is adjusted, the middle frame 1600 can lock the at least two support plates 1200, so as to avoid the relative position of the two adjacent support plates 1200 from shifting due to factors such as transportation during the subsequent assembly process.

[0040] From the above content, it can be seen that, on the one hand, this embodiment accurately adjusts the splicing gap between two adjacent support plates 1200 through the connecting member 1400 to ensure that the gap between the display screens 2000 meets the requirements. On the other hand, the setting of the middle frame 1600 can not only avoid the position of the adjusted support plate 1200 being affected by the position of the other support plate 1200 being adjusted during the splicing gap adjustment process, but also avoid the relative position between at least two support plates 1200 being offset due to factors such as transportation after the splicing gap is adjusted.

[0041] In this embodiment, the middle frame 1600 and at least two support plates 1200 are relatively fixed to each other via magnetic attraction. Specifically, when no external force is applied to the middle frame 1600 and support plates 1200, they remain relatively stationary. When external force is applied to a support plate 1200, the support plate 1200 slides on the middle frame 1600, thereby adjusting the relative position of the support plates 1200.

[0042] See Figure 4 In this embodiment, a magnetic member 1201 is installed on the support plate 1200, and the middle frame 1600 is made of a material attracted by the magnetic member 1201, so that the magnetic member 1201 and the middle frame 1600 attract each other, making the support plate 1200 and the middle frame 1600 relatively fixed.

[0043] The magnetic element 1201 may be a magnet such as a neodymium iron boron magnet or an iron chromium cobalt magnet, and the material of the middle frame 1600 may be at least one of iron, cobalt, and nickel.

[0044] In this embodiment, the support plate 1200 is also made of a material attracted by the magnetic element 1201, so that the support plate 1200 and the magnetic element 1201 are fixedly connected by magnetic attraction. In other embodiments, the magnetic element 1201 can also be fixed to the support plate 1200 by means of clipping, gluing, etc.

[0045] In an application scenario, such as Figure 6As shown, to ensure the stability of the support plate 1200 when placed on the middle frame 1600 and to ensure the fit between the support plate 1200 and the middle frame 1600, a groove 1202 is provided on the surface of the support plate 1200 facing the middle frame 1600, and the magnetic member 1201 is disposed in the groove 1202. The thickness of the magnetic member 1201 is equal to or less than the depth of the groove 1202.

[0046] It should be noted that the present application does not limit the specific connection method between the support plate 1200 and the middle frame 1600. For example, in other embodiments, the support plate 1200 and the middle frame 1600 are fixedly connected by bonding, in which case the middle frame 1600 is coated with an adhesive. When no external force is applied to the support plate 1200, the support plate 1200 and the middle frame 1600 remain relatively stationary under the action of the adhesive. When an external force is applied to the support plate 1200, the support plate 1200 overcomes the adhesive force of the adhesive (i.e., the binding force in the first direction) and moves relative to the middle frame 1600. Alternatively, both the support plate 1200 and the middle frame 1600 are provided with magnetic members 1201, and the support plate 1200 and the middle frame 1600 are relatively fixed by the binding force in the first direction through the mutual attraction between the magnetic members 1201. Alternatively, the support plate 1200 and the middle frame 1600 are made of mutually attractive magnetic materials, in which case the magnetic member 1201 is not required.

[0047] See Figure 7 Similar to the support plate 1200 , in order to allow the connector 2001 on the display screen 2000 to introduce a driving signal, a second opening B corresponding to the first opening A is opened on the middle frame 1600 to expose the connector 2001 .

[0048] Because the relative position between the support plate 1200 and the middle frame 1600 can be adjusted by external force, that is, the support plate 1200 and the middle frame 1600 are not locked together, the position of the support plate 1200 may still shift after the gap between the support plates 1200 is adjusted, thereby failing to meet the required gap between two adjacent display screens 2000. For example, when the support plate 1200 and the middle frame 1600 are placed vertically, the support plate 1200 may shift under the force of gravity.

[0049] To avoid the above defects, see Figure 3 In this embodiment, the splicing mechanism 1000 also includes a locking member 1800 for locking the support plate 1200 and the middle frame 1600, so that the splicing seam between the two display screens 2000 cannot be adjusted by external force, and the position of the support plate 1200 will not change during use.

[0050] Specifically, after the gap between the at least two support plates 1200 is adjusted, the locking member 1800 locks the at least two support plates 1200 to the middle frame 1600. Specifically, during the gap adjustment process, the locking member 1800 is not in a locked state, and only after the adjustment is completed does the locking member 1800 enter a locked state.

[0051] In this embodiment, combined with Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 as well as Figure 9 A first threaded hole 1203 is provided on the surface of the support plate 1200 facing the middle frame 1600, and the middle frame 1600 is provided with a countersunk hole 1610. The countersunk hole 1610 includes a first through hole 1611 and a second through hole 1612 that are connected. The diameter of the first through hole 1611 is larger than the diameter of the second through hole 1612, so that a step portion 1613 is formed on the side wall of the countersunk hole 1610. The diameter of the second through hole 1612 is larger than the diameter of the first threaded hole 1203.

[0052] The locking member 1800 includes a first rod body 1810 and a stop plate 1820. The first end of the first rod body 1810 is provided with a first external thread 1801 that cooperates with the first threaded hole 1203. The stop plate 1820 is arranged on the periphery of the second end of the first rod body 1810. After the first end of the first rod body 1810 passes through the first through hole 1611 and the second through hole 1612 in sequence and enters the first threaded hole 1203 and is locked with the first threaded hole 1203, the stop plate 1820 abuts against the step portion 1613.

[0053] Specifically, the diameter of the second through hole 1612 is set to be larger than the diameter of the first threaded hole 1203, so that when the support plate 1200 moves arbitrarily relative to the middle frame 1600 within the allowed range, the first end of the first rod body 1810 can pass through the first through hole 1611 and the second through hole 1612 and enter the first threaded hole 1203. In other words, the diameter of the second through hole 1612 is set to be larger than the diameter of the first threaded hole 1203, which reserves space for adjusting the splicing gap between two adjacent support plates 1200.

[0054] It should be noted that, in other embodiments, the locking member 1800 may not be provided. Accordingly, the first threaded hole 1203 may not be provided on the support plate 1200 , and the countersunk hole 1610 may not be provided on the middle frame 1600 .

[0055] Combine Figure 3 、 Figure 6 、 Figure 10 as well as Figure 11One of the two adjacent support plates 1200 is connected to a first connecting portion 1210, and the other is connected to a second connecting portion 1220. The ends of the connecting member 1400 are connected to the first connecting portion 1210 and the second connecting portion 1220, respectively. The connection position between at least one of the first connecting portion 1210 and the second connecting portion 1220 and the connecting member 1400 is adjustable, thereby achieving an adjustable splicing gap between the two adjacent support plates 1200. In other words, the splicing gap between the two adjacent support plates 1200 is adjusted by adjusting the connection position between the connecting member 1400 and at least one of the first connecting portion 1210 and the second connecting portion 1220.

[0056] It should be noted that, in other embodiments, the joint gap between two adjacent support plates 1200 can also be adjusted by the connector 1400 itself. For example, the connector 1400 can be a telescopic member with an adjustable length, so that the width of the joint gap between two adjacent support plates 1200 can be adjusted. Alternatively, the connector 1400 can be a hinged structure, which can adjust the relative angle between two adjacent support plates 1200.

[0057] At the same time, in this embodiment, one side edge of each support plate 1200 is simultaneously connected to a first connection portion 1210 and a second connection portion 1220, wherein the first connection portion 1210 and the second connection portion 1220 connected to the same side edge of each support plate 1200 are respectively connected to the second connection portion 1220 and the first connection portion 1210 connected to the same side edge of another adjacent support plate 1200 through different connecting members 1400.

[0058] Specifically, two adjacent support plates 1200 are defined as a first support plate and a second support plate, respectively. In this embodiment, the first edge of the first support plate adjacent to the second support plate is connected to the first connection portion 1210 and the second connection portion 1220 at the same time, and the second edge of the second support plate adjacent to the first support plate is also connected to the first connection portion 1210 and the second connection portion 1220 at the same time, wherein the first connection portion 1210 of the first edge is connected to the second connection portion 1220 of the second edge through the connecting member 1400, and the second connection portion 1220 of the first edge is connected to the first connection portion 1210 of the second edge through the connecting member 1400.

[0059] According to the principle of "two points determine a line", one side edge of the support plate 1200 is set to connect the first connection part 1210 and the second connection part 1220 at the same time, so that two adjacent support plates 1200 are connected by two connecting members 1400, which can ensure the stability of the position adjustment between the two adjacent support plates 1200. Compared with the two adjacent support plates 1200 being connected by only one connecting member 1400, the relative position of the two adjacent support plates 1200 can be more conveniently controlled.

[0060] In other embodiments, the first edge of the first support plate facing the second support plate may be connected to two first connection portions 1210 , and the second edge of the second support plate facing the first support plate may be connected to two second connection portions 1220 .

[0061] Meanwhile, in other embodiments, two adjacent support plates 1200 may also be connected by only one connecting member 1400 .

[0062] In this embodiment, the first connecting portion 1210 is protruded from the surface of the support plate 1200 facing the middle frame 1600, and the first connecting portion 1210 is provided with a second threaded hole 1211, the extension direction of the second threaded hole 1211 is parallel to the plate surface of the support plate 1200, and the connecting member 1400 includes a second rod body 1401, and the first end of the second rod body 1401 is provided with a second external thread 1410 that cooperates with the second threaded hole 1211. The connection position of the connecting member 1400 and the first connecting portion 1210 is adjustable through the cooperation of the second threaded hole 1211 and the second external thread 1410.

[0063] Specifically, the first end of the second rod body 1401 is connected to the first connecting part 1210 through a threaded connection. Through the cooperation between the second external thread 1410 and the second threaded hole 1211, the length of the connecting member 1400 extending into the second threaded hole 1211 can be adjusted, thereby achieving adjustable connection position between the connecting member 1400 and the first connecting part 1210, and ultimately achieving adjustable splicing gap between two adjacent support plates 1200.

[0064] At the same time, since the pitch of the second external thread 1410 on the connector 1400 can be known in advance, the adjustment of the seam between the two adjacent support plates 1200 can be accurately controlled, and the adjustment accuracy of the seam can be brought to the micron level. For example, when the pitch of the second external thread 1410 is 0.35mm, if the connector 1400 is rotated 360°, the distance between the two adjacent support plates 1200 will move 0.35mm. If the connector 1400 rotates 10° as a gear, then the distance between the two adjacent support plates 1200 will move 9.7μm for each gear adjustment. When the pitch of the second external thread 1410 is smaller, the adjustment accuracy between the two adjacent support plates 1200 can be even higher, ultimately achieving the height adjustment of the splicing gap in the spliced ​​large screen.

[0065] The second connecting portion 1220 is protruded from the surface of the support plate 1200 facing the middle frame 1600. The second connecting portion 1220 is provided with a through slot 1221. The extension direction of the through slot 1221 is parallel to the plate surface of the support plate 1200. The connecting member 1400 also includes a clamping portion 1420 provided at the second end of the second rod body 1401. When the second end of the second rod body 1401 enters the through slot 1221, as the second rod body 1401 moves, the clamping portion 1420 is clamped with the second connecting portion 1220, so that the second rod body 1401 and the connecting member 1400 move synchronously.

[0066] Specifically, during the splicing process, after locking the first end of the second rod body 1401 with the first connecting part 1210, the second end of the second rod body 1401 falls into the through groove 1221. Then, when it is necessary to adjust the splicing seam between the two adjacent support plates 1200, the second rod body 1401 is rotated to make it move. During the movement of the second rod body 1401, the clamping part 1420 will be clamped with the second connecting part 1220, causing the second connecting part 1220 to move synchronously, and then causing the support plate 1200 corresponding to the second connecting part 1220 to move synchronously, thereby changing the splicing seam between the two adjacent support plates 1200.

[0067] In order to ensure that the support plate 1200 and the middle frame 1600 fit together, the middle frame 1600 is provided with a hollow area 1601 to expose the first connection portion 1210 , the second connection portion 1220 and the connection member 1400 .

[0068] In this embodiment, the first connection portion 1210 and the second connection portion 1220 are both block-shaped.

[0069] Among them, combined Figure 6 as well as Figure 11 The through-slot 1221 is provided on the surface of the second connecting portion 1220 facing away from the support plate 1200, which can prevent the connector 1400 from being separated from the second connecting portion 1220 during adjustment. It should be noted that in other embodiments, the through-slot 1221 can also be provided on the surface where the second connecting portion 1220 is connected to the support plate 1200.

[0070] Combine Figure 11 and Figure 12 The clamping portion 1420 includes a first limiting plate 1421 and a second limiting plate 1422 which are arranged on the periphery of the second end of the second rod body 1401 and are arranged opposite to each other. When the second end of the second rod body 1401 enters the through groove 1221, the first limiting plate 1421 and the second limiting plate 1422 are respectively arranged on two opposite sides of the second connecting portion 1220 to limit the second connecting portion 1220 between the first limiting plate 1421 and the second limiting plate 1422.

[0071] Specifically, the arrangement of the first limiting plate 1421 and the second limiting plate 1422 enables the second connecting portion 1220 to move synchronously when the second rod 1401 moves toward or away from the first connecting portion 1210 .

[0072] For ease of explanation, as follows Figure 10 As shown, the X direction and the Y direction are defined, and the direction perpendicular to both the X direction and the Y direction is defined as the Z direction, and the portion of the second rod 1401 between the first limiting plate 1421 and the second limiting plate 1422 is defined as the limiting portion 1402 .

[0073] In this embodiment, in order to allow the through slot 1221 to reserve a gap for the limiting portion 1402 in the X and Y directions, the interval between the first limiting plate 1421 and the second limiting plate 1422 is greater than the length of the through slot 1221, and the width of the through slot 1221 is greater than the width of the connecting member 1400 at the limiting portion 1402; in order to allow the through slot 1221 to reserve a gap for the limiting portion 1402 in the Z direction, the shortest distance from the side wall of the second threaded hole 1211 to the support plate 1200 is greater than the shortest distance from the side wall of the through slot 1221 to the support plate 1200.

[0074] Specifically, the gaps reserved in the X and Y directions are intended to leave rotational adjustment space between the two adjacent support plates 1200. That is, in the process of adjusting the seam, the second rod body 1401 can be set in parallel with the extension direction of the through groove 1221, or the second rod body 1401 can be set in non-parallel with the extension direction of the through groove 1221, so that a predetermined angle of rotation can occur between the two adjacent support plates 1200.

[0075] The gap reserved in the Z direction is to reserve installation allowance to avoid interference. Specifically, due to the existence of processing tolerances, the thickness of different display screens 2000 may be different. When the thickness of the display screen 2000 is different, if the shortest distance from the side wall of the second threaded hole 1211 to the support plate 1200 is equal to or less than the shortest distance from the side wall of the through groove 1221 to the support plate 1200, the second rod body 1401 will not be able to be inserted into the second threaded hole 1211. In order to avoid this phenomenon, the shortest distance from the side wall of the second threaded hole 1211 to the support plate 1200 is set to be greater than the shortest distance from the side wall of the through groove 1221 to the support plate 1200.

[0076] It should be noted that, in other embodiments, the through slot 1221 may be provided to reserve a gap for the limiting portion 1402 only in one or two directions of X, Y, and Z, or no gap may be reserved in the X, Y, and Z directions, for example, the second end of the second rod body 1401 is fixedly connected to the second connecting portion 1220.

[0077] See Figure 12In order to facilitate the adjustment of the connecting member 1400, the end surface of the second rod body 1401 is further provided with an adjustment groove 1403 to facilitate the insertion of tools such as a screwdriver.

[0078] The second rod 1401 , the first limiting plate 1421 , and the second limiting plate 1422 may be integrally formed or connected together via a connecting structure, which is not limited herein.

[0079] See Figure 13 and Figure 14 In another embodiment of the present application, the electronic device 3000 includes a display screen 3100 , a splicing mechanism 3200 , a connecting line 3300 , and a splicing box 3400 .

[0080] Among them, the structures of the display screen 3100, the splicing mechanism 3200, and the connecting line 3300 are the same as those of the display screen, the splicing mechanism, and the connecting line in the above embodiment. For details, please refer to the above embodiment and will not be repeated here.

[0081] The splicing box 3400 houses the display screens 3100 and the splicing mechanism 3200. The middle frame of the splicing mechanism 3200 is fixed to the splicing box 3400. A driver board 3410 is mounted on the splicing box 3400. Each display screen 3100 is connected to the driver board 3410 via a corresponding connection line 3300. The driver board 3410 outputs a driving signal to enable the display screens 3100 to display normally.

[0082] The number of the splicing boxes 3400 may be one or more. When there are more than one splicing boxes 3400 , the multiple splicing boxes 3400 are spliced ​​together to form an electronic device 3000 of a larger size.

[0083] The electronic device 3000 may be any device with a display function, such as a mobile phone, a computer, a television, etc., and is not limited here.
